Microwave Buttermilk Pralines

Combine sugar, soda, buttermilk and butter in large (3-4 quart) microwave or glass bowl. Microwave 5 minutes on medium, uncovered, to melt. Stir until butter is blended. Microwave on medium, uncovered, for 22-25 minutes or until soft ball stage. Add vanilla, beat with mixer until mixture forms soft peaks. Mix in pecans before finishing beating, if desired. Drop by teaspoons onto wax paper to make patties. If you prefer to have the pecans on top, place them on at this point instead of mixing them in before. If it gets stiff while dropping, heat briefly in the microwave. Cool until firm. Store in airtight container.
